QColorDrag(3qt) QColorDrag(3qt) NAME
QColorDrag - Drag and drop object for transferring colors SYNOPSIS
#include <qdragobject.h> Inherits QStoredDrag. Public Members QColorDrag ( const QColor & col, QWidget * dragsource = 0, const char * name = 0 ) QColorDrag ( QWidget * dragsource = 0, const char * name = 0 ) void setColor ( const QColor & col ) Static Public Members bool canDecode ( QMimeSource * e ) bool decode ( QMimeSource * e, QColor & col ) DESCRIPTION
The QColorDrag class provides a drag and drop object for transferring colors. This class provides a drag object which can be used to transfer data about colors for drag and drop and in the clipboard. For example, it is used in QColorDialog. The color is set in the constructor but can be changed with setColor(). For more information about drag and drop, see the QDragObject class and the drag and drop documentation. See also Drag And Drop Classes. MEMBER FUNCTION DOCUMENTATION
QColorDrag::QColorDrag ( const QColor & col, QWidget * dragsource = 0, const char * name = 0 ) Constructs a color drag object with the color col. Passes dragsource and name to the QStoredDrag constructor. QColorDrag::QColorDrag ( QWidget * dragsource = 0, const char * name = 0 ) Constructs a color drag object with a white color. Passes dragsource and name to the QStoredDrag constructor. bool QColorDrag::canDecode ( QMimeSource * e ) [static] Returns TRUE if the color drag object can decode the mime source e; otherwise returns FALSE. bool QColorDrag::decode ( QMimeSource * e, QColor & col ) [static] Decodes the mime source e and sets the decoded values to col. void QColorDrag::setColor ( const QColor & col ) Sets the color of the color drag to col.

QImageDrag - Drag and drop object for transferring images SYNOPSIS
#include <qdragobject.h> Inherits QDragObject. Public Members QImageDrag ( QImage image, QWidget * dragSource = 0, const char * name = 0 ) QImageDrag ( QWidget * dragSource = 0, const char * name = 0 ) ~QImageDrag () virtual void setImage ( QImage image ) Static Public Members bool canDecode ( const QMimeSource * e ) bool decode ( const QMimeSource * e, QImage & img ) bool decode ( const QMimeSource * e, QPixmap & pm ) DESCRIPTION
The QImageDrag class provides a drag and drop object for transferring images. Images are offered to the receiving application in multiple formats, determined by Qt's output formats. For more information about drag and drop, see the QDragObject class and the drag and drop documentation. See also Drag And Drop Classes. MEMBER FUNCTION DOCUMENTATION
QImageDrag::QImageDrag ( QImage image, QWidget * dragSource = 0, const char * name = 0 ) Constructs an image drag object and sets its data to image. dragSource must be the drag source; name is the object name. QImageDrag::QImageDrag ( QWidget * dragSource = 0, const char * name = 0 ) Constructs a default image drag object. dragSource must be the drag source; name is the object name. QImageDrag::~QImageDrag () Destroys the image drag object and frees up all allocated resources. bool QImageDrag::canDecode ( const QMimeSource * e ) [static] Returns TRUE if the information in mime source e can be decoded into an image; otherwise returns FALSE. See also decode(). Example: desktop/desktop.cpp. bool QImageDrag::decode ( const QMimeSource * e, QImage & img ) [static] Attempts to decode the dropped information in mime source e into img. Returns TRUE if successful; otherwise returns FALSE. See also canDecode(). Example: desktop/desktop.cpp. bool QImageDrag::decode ( const QMimeSource * e, QPixmap & pm ) [static] This is an overloaded member function, provided for convenience. It behaves essentially like the above function. Attempts to decode the dropped information in mime source e into pixmap pm. Returns TRUE if successful; otherwise returns FALSE. This is a convenience function that converts to a QPixmap via a QImage. See also canDecode(). void QImageDrag::setImage ( QImage image ) [virtual] Sets the image to be dragged to image. You will need to call this if you did not pass the image during construction. SEE ALSO
